It seems this was caused my me having libclamav5 installed after I tried to install clamav from source.
I've since tried this again (removing libclamav5 first), then installing clamav via "aptitude" with no issues. -- package clamav-base None failed to install/upgrade: subprocess post-installation script returned error exit status 1 https://bugs.launchpad.net/bugs/293308 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
